Add option to winebuild to disable ASLR/dynamicbase
by Tres Finocchiaro 09 Jul '25

09 Jul '25

Hi, I'm a maintainer of LMMS and we use a wine bridge for loading 32-bit and 64-bit VST plugins into the Linux version of our software. We've recently updated our build tools and noticed that some of our older 64-bit VSTs fail to load. After a lot of back and forth, we've isolated the issue to the following wine commit: > Commit 518e394 julliard committed on Sep 25, 2023 > winebuild: Set ASLR-related dll flags by default. > https://github.com/wine-mirror/wine/commit/518e394794160818ffe6826c874ff2f5… One of our developers has proposed a patch which reverts this behavior here: https://github.com/Fastigium/winebuild/commit/7f9e27e44cfb8eba79f3850f46e12… My questions are as follows: 1. Would winehq be receptive to a winebuild flag that allows the old behavior? 2. If acceptable, would you prefer LMMS author this patch, or is this change trivial enough/small enough that the winehq team would prefer to tackle it themselves? 3. Lastly, quoting a past mailing list convo, should we be doing our wine bridge differently? Currently we build RemovePluginVst64.so.exe. "[...] I don't think we have any plans to deliberately break the old all-in-one .dll.so binaries. It is quite likely that this functionality will bitrot over time though. Also the functionality that the PE/unix split was introduced for won't be available that way [...]" Source: https://list.winehq.org/mailman3/hyperkitty/list/wine-devel(a)winehq.org/me… Thanks kindly for your time, -Tres - Tres.Finocchiaro(a)gmail.com

wine and safearray marshalling
by Ilya Sokolov 30 Jun '25

30 Jun '25

Hello I have a question about how WINE processes marshalling between .Net Core code and COM object. There is an application, which runs in x64 prefix. Application contains COM object and .Net Core user interface. Data between the com object and the UI are transmitted in structures, which contains safearrays of other structures, some of structures include BSTRs. Some example of code is listed below: typedef [uuid(59d7e939-2a40-4d4c-a750-e8bd85f08a77)] > struct stLimitsSettings > { > float AbortMinus; > float AbortPlus; > float MaxDriveVoltage; > float MaxShakerAcc; > float MaxShakerDisp; > float MaxShakerVel; > float MaxVDivGForRunning; > float MaxVDivGForStartup; > int PhusicalUnitIndex; > float ProductMass; > BSTR ShakerProducerName; > enLimitAndLevelUnitType TolAndAbortUnits; > float TolMinus; > float TolPlus; > int UnexceedLimitsNum; > float UnExceedAverAlpha; > float UnExceedStableLinePrec; > BSTR ShakerModelName; > BOOL CheckShakerLimits; > float SpectOutOfLimitsPers; > BOOL UseSigmaClippingInCheck; > enShkLimitType ShkLimitType; > > BOOL useMultyShkUnExFullLimits; > > stDetailedMassDesc DetailedMass; > BOOL LimitRandomLinesOutsideTheProfile; > > > float > LinesOutsideTheBorder; > > > BOOL > UseTableLimits; > > enWhatToLiminInRndSpectrum WhatToLimitInSpectrum; > float AbDDBSpectrumPlus; > float AbDDBSpectrumMinus; > float TolDDBSpectrumPlus; > float TolDDBSpectrumMinus; > enLimitAndLevelUnitType SpectrumLimitUnitType; > BOOL DisableLowLimitWhileOnNotching; > SAFEARRAY(stShkLimitPair) LimitsTable > SAFEARRAY(stChUnexceedLimit) UnexceedChParameters; > > BOOL CheckChannelsOnOverload; > }stLimitsSettings; > > > typedef [uuid(311D09EA-7943-4A18-ADAB-CFE991E4A3D1), > struct stSyntheseSRSPoint > { > float Freq; > float Responce; > float NegativeMax; > float PositiveMax; > } stSyntheseSRSPoint; > cpp_quote("struct > __declspec(uuid(\"{311D09EA-7943-4A18-ADAB-CFE991E4A3D1}\")) > stSyntheseSRSPoint;") > > typedef [uuid(6A8B679F-E7C6-45F6-A0DB-378D2E4CD0ED), > struct stSRSPointsFromSynthese > { > int PointsCount; > SAFEARRAY(stSyntheseSRSPoint) SRSPoints; > }stSRSPointsFromSynthese; > > typedef [uuid(747684a8-7b15-4215-8484-7e674fce3e16), > struct stSRSProfilesDescription > { > int ID; > BSTR Name; > float EndAcc; > float EndVel; > float EndDisp; > float MaxAcc; > float MaxVel; > float MaxDisp; > float PWA; > DWORD CompencateSeed; > stSRSSyntheseSettings SyntheseSettings; > stSRSTable SRSTable; > stWaveletsTable Wavelets; > stSRSPointsFromSynthese SynthesePoints; > DWORD RealShkLenInSamples; > float RealSampleRate; > }stSRSProfilesDescription; > cpp_quote("struct > __declspec(uuid(\"{747684a8-7b15-4215-8484-7e674fce3e16}\")) > stSRSProfilesDescription;") > > > typedef [uuid(d4b7ee82-d6ca-4131-9ab2-1c0ca9093935), > struct stMosaSRSProfiles > { > int ProfilesCount; > float MaxAcc; > float MaxVel; > float MaxDisp; > float EndAcc; > float EndVel; > float EndDisp; > float ShkTimeInSec; > double Te; > double TeConc; > SAFEARRAY(stSRSProfilesDescription) Profiles; > }stMosaSRSProfiles; > > typedef [uuid(ee6226d6-3ac9-47b4-aab3-3e1d612b8c69), > struct stMosaSRSTestSettingsStruct > { > BOOL IsReportSettingsInited; > BOOL TestStartQuestState; > DWORD TestTimeInSec; > DWORD TotalShkCount; > int ActiveOutputsCount; > int AxisesCount; > SAFEARRAY(stMultishakerOutputLimitsDescription) OutputLimits; > stMosaSRSProfiles TestProfiles; > stMultishTaskToAxisMap Axises; > stMultishakerReportSettings ReportSettings; > stAnalyseSettings AnalysesSettings; > stChannelsConfigSettings ChannelsConfig; > stControlSettings ControlSettings; > stLimitsSettings Limits; > stSchedule Schedule; > stDataSaveSettings DataSaveSettings; > }stMosaSRSTestSettingsStruct; > > Sometimes getting data woks well, however sometimes an error appears with log which looks like: 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:advapi:RegisterEventSourceW ((null),L".NET Runtime"): stub > 06e8:fixme:advapi:ReportEventW > (00000000CAFE4242,0x0001,0x0000,0x00000402,0000000000000000,0x0001,0x00000000,00007FFFFE27A7F0,0000000000000000): > stub > 06e8:err:eventlog:ReportEventW L"Application: VisProbe_SL.exe\n" > 06e8:err:eventlog:ReportEventW L"CoreCLR Version: 8.0.1425.11118\n" > 06e8:err:eventlog:ReportEventW L".NET Version: 8.0.14\n" > 06e8:err:eventlog:ReportEventW L"Description: The process was terminated > due to an unhandled exception.\n" > 06e8:err:eventlog:ReportEventW L"Exception Info: > System.AccessViolationException: Attempted to read or write protected > memory.

DXVK + DComp causes graphics rendering to fail
by zhengxianwei 29 Jun '25

29 Jun '25

I'm not sure whether this issue should be posted on the DXVK forum or here. If I've posted it in the wrong place, I apologize. I wrote a test program called dcomp_test.exe, which is already working under Wine. Its main function is to render circles, and the effect looks like this: [image: image.png] The actual operation is...： surface content = gdi * backgroup_alpha + swapchain[0] * foreground_alpha However, after replacing Wine's built-in DLLs with the ones I built from DXVK specifically dxgi, d3d8, d3d9, d3d10core, d3d11, and d3d12 I found that the circle was no longer rendered. The image extracted from the swapchain contained all zeros. [image: image.png] I did a quick trace and confirmed that it reached: 1. ID3D11DeviceContext1_DrawIndexed 2. ID3D11DeviceContext1_Draw https://github.com/wine-mirror/wine/blob/80bc1338bea7d9dac78ab449b4505e5bb9… So I feel that the circle is indeed being rendered onto the DXVK D3D11 swapchain, but I'm not sure at which step the content fails to be retrieved correctly. Any suggestions are welcome

How long after XFlush is called does the screen typically refresh correctly?
by zhengxianwei 29 Jun '25

29 Jun '25

I wrote a small test program that modifies a region using BitBlt, then checks the color of that region. I found that even immediately after BitBlt, it takes over 80 milliseconds before the correct color can be reliably detected. Then, I added an XSync(gdi_display, False) after the XFlush in x11drv_surface_flush, and the delay dropped to around 50–60 milliseconds. Is this expected? I was hoping that after BitBlt, the updated color could be detected immediately, without needing to add a delay or jitter. But it seems that XFlush only pushes the commands to the X server, and is not like vkQueuePresentKHR with semaphores or fences, which signal that the data has been pushed to the display (even though that still doesn’t guarantee vertical scanout completion).

Issues in OpenGL 16bpp formats support
by vyacheslav.chigrin＠izba.dev 20 Jun '25

20 Jun '25

Hello, Two years ago I locally fixed some bug with Civilization III game, caused by problems with 16bpp format support in OpenGL on joint of Wine and Mesa libraries. I described my findings here https://bugs.winehq.org/show_bug.cgi?id=41930#c60 Now realized that may be bugtracker alone is not enough, and may be writing to this e-mail list is better. I'm wondering if anybody interesting in fixing this issue? I will be glad to work with somebody to fix this problem in the main Wine brunch (just don't know correct workflow for upstreaming and discussing fixes like that). With best regards, Vyacheslav Chigrin

Does the timing of composition need to be moved from dcomp.dll to win32u?
by zhengxianwei 19 Jun '25

19 Jun '25

Zhiyi Zhang provided an implementation of DComp composition： https://gitlab.winehq.org/zhiyi/wine/-/commit/ef4f90c2ae909f4a732f0ebeae3b7… I created a simple sample that renders three equally sized red circles with varying alpha values on a plain white background window. On Windows, it displays as follows. [image: dcomp_test_window.png] But on Linux, it display as follows. [image: dcomp_test_wine.png] One of the main issues here is that the background turns black. This is because the foreground (swapchain) is not alpha-blended with the background (GDI); instead, it is simply overlaid using BitBlt. ``` * BitBlt(dst_dc, 0, 0, rect.right - rect.left, rect.bottom - rect.top, src_dc, 0, 0, SRCCOPY);* ``` So I added an alpha_blend step here instead of simply using the original BitBlt. ``` s1 = src_data; d1 = dst_data; for (int i = 0; i < height; i++) { for (int j = 0; j < width; j++) { // src is alpha pre multiple float bg_alpha = ((255.f - s1[3])) / 255; d1[0] = (d1[0] * bg_alpha) + s1[0]; d1[1] = (d1[1] * bg_alpha) + s1[1]; d1[2] = (d1[2] * bg_alpha) + s1[2]; s1 += 4; d1 += 4; } } //iret = SetDIBits(dst_hdc, dst_bitmap, 0, height, dst_data, &bmi, DIB_RGB_COLORS); iret = SetDIBitsToDevice(dst_hdc, 0, 0, width, height, 0, 0, 0, height, dst_data, &bmi, DIB_RGB_COLORS); ``` The new display effect is as follows. [image: dcomp_test_wine_alpha_blend.png] It looks like basic blending is working, but the alpha values of the circles are lost. After analyzing the issue, I found the following cause. I'll draw a diagram to briefly illustrate the cause of this issue. My original expectation of the image generation process [image: flush1.png] But the actual process is as follows [image: image.png] After the bitmap is alpha-blended and displayed on the screen, it is retrieved again in the next frame and repeatedly involved in alpha blending — resulting in redundant computations. I personally think that a more reasonable solution would be to insert window_surface_composition within window_surface_flush to more thoroughly resolve these kinds of issues [image: image.png] During window_surface_flush, composite the current surface with the swapchain's surface into an offscreen surface, then flush that to the screen. This way, the original window surface won't be affected. I'm trying to fix this issue now — do you have any suggestions?

Is it normal that the COM vtbl structure cannot be aligned between Windows and Wine
by zhengxianwei 11 Jun '25

11 Jun '25

In wine, Visual2Vtbl ``` typedef struct IDCompositionVisual2Vtbl { BEGIN_INTERFACE /*** IUnknown methods ***/ HRESULT (STDMETHODCALLTYPE *QueryInterface)( IDCompositionVisual2 *This, REFIID riid, void **ppvObject); ULONG (STDMETHODCALLTYPE *AddRef)( IDCompositionVisual2 *This); ULONG (STDMETHODCALLTYPE *Release)( IDCompositionVisual2 *This); /*** IDCompositionVisual methods ***/ HRESULT (STDMETHODCALLTYPE *SetOffsetX)( IDCompositionVisual2 *This, float offset_x); HRESULT (STDMETHODCALLTYPE *SetOffsetXAnimation)( IDCompositionVisual2 *This, IDCompositionAnimation *animation); HRESULT (STDMETHODCALLTYPE *SetOffsetY)( IDCompositionVisual2 *This, float offset_y); ``` setOffsetX (float *) at offset 0x18 [image: visual2vtbl.png] But in windows 0x18 is setOffsetX (Animation *) Is this correct?
